A marginal wind profile but sufficient CAPEs and an east-west
outflow boundary in the Texas panhandle made supercells a possibility
The ground teams spent the night in Amarillo and performed damage surveys
in the area of Dimmitt and Friona, Texas this morning.
The P-3 and Electra departed OKC at 1914 UTC and headed southwest for Childress, TX and on to Tulia, TX. The outflow boundary extended westward along the Red River to Tulia and Friona and northwestward into northeast New Mexico. The aircraft began an INIT pattern with the P-3 performing stepped traverses between Muleshow and Friona, TX at 2115 UTC. One main boundary and several smaller boundaries were encountered.
The FC committed on a cell northwest of us near Glenrio, TX at 2148 UTC. We made 8 radar passes as the storm showed some signs of life with several hooks and tops to 17 km before the FC cancelled operations on this storm to focus on storms developing near Silverton, TX some 50-60nm east-southeast.
The aircraft spent the greater part of an hour trying to find a way to fly patterns on this convection. Much of the boundary from Silverton eastward was filled with convective towers and TCu. We finally settled on the westernmost cell only to find the ground teams on the next cell east. We then tried an east-west pattern along the southern flank of this cell but low clouds and turbulence forced us south.
We departed the area at 0124 UTC, noting 5 principal cells lined up along the east-west boundary with the easternmost cell on the Oklahoma- Texas border. We hightailed it back to OKC due to a severe cell near El Reno with a prominent hook. We landed at 0208 UTC, consuming 7.1 flight hours; 9.1 hours remain.
